Set up connections between two BluetoothBee step by step

Hy,

i have a bluetooth master/slave device.

The device is configured as master, but i have a problem!

I have a laptop pc and a bluetooth master/slave configured as master.

If i try to discover devices using the bluetooth device i find my pc and can connect to the pc, but i want also to do the oposite, but my laptop pc doesn’t find the bluetooth module!
How can i put the master device in discoverable mode?

Thanks
